Purpose: Differential locks help prevent wheel spin and loss of power when one wheel encounters mud, snow or other slippery surfaces. When climbing or traversing slopes, keeping the wheels at equal speeds is critical for stability and to prevent skidding. The differential lock pedal allows the tractor to power both rear wheels evenly, reducing the risk of wheel idling and ensuring safer travel up or down slopes. By ensuring both rear wheels move together, the tractor maintains a more stable and controlled path, reducing the risk of getting stuck or losing control.
